yep, 'nother past mecurichrome patient here, as well as one called Methialade (sp?). This goes back to the 60s. Can remember various strips of body real estate having been painted with both of those. Back then many of us would try to sneak away on minor scrapes in hopes of avoiding the "oh, no, not Methialade!" stinging/burning factor, but moms had a way of hunting us down...........until along came a kinder, gentler Bactine.
